NZ$379 pair 800cc or 1000cc denso injectors to suit
vs
NZ$400 pair 800cc Sard injectors to suit
vs
NZ$900 pair 1000cc Sard injectors to suit

im upgrading my S5 turbo compressor housing and wheel to a TO4 .60 AR with a 48mm wheel. i'll be tuning with a SAFC and a wideband
looking at running 1 bar-1.2 bar ( unless these injectors wont be enough, then i'll run less )

clearly the 1000cc sard injectors ar very expensive,

I can get 1680cc injecotrs for $300 for a pair but i think that will be over kill and the SAFC wont handle them

are denso injecotors ok?

 

I'd search froogle for better prices.

 

those preety steep are they? hmmm, stupid NZ, all the way down here and have expensive prices.

 

dang.....I'd go to speedmachine and grab some new RCEngineering injectors. They're about $95 a piece for stock flow through 1000cc. I think the 1600s are a tad more.

Even if shipping is 150 dollars you'll still be a head of the eight ball.

 

ok sweet so im gona find better prices and most likely import them in.

So what size injectors will i need? please dont ask me how much HP i want to make, please try and think of it as a question or airflow/mass vs fuel. I want to be able to supply enough fuel to suit that turbo ( its not very big really so i don think id need much)

 

I'd go 720cc(or 750)primary and 800cc secondary. Should be able to trim enough out of those to make decent driveability. And a 750cc won't make your idle super rich........richer then now, but nothing overkill.

But pssssst *standalone* lol

 

psssst. shooshie.
Id love to go stand alone but i honestly dont have the paitenice to save $50 per week till i get to 2000 to buy one ( and all assoicited mods adn some v.basic tuning)

I just done some research and its a 48mm inducer wheel. similar to a TO4E

 

i guess i can also lean out the idol with the adjuster thingy next to the boost sensor and also lean it out with the safc.

The Fcon does lean out the lower rpms while in vacuum so it should help.

any more opinions on injector sizing?

The guy i brought it off was runing a S5 turbo on a 12a and making 300whp at 20psi and it would drop from 20 at 7000 to -15 psi at 8500. he was only running 2x 550's adn 2x 560cc and a standalone, but the bik key factor here is 12A

 

Apexi power fc/commander $700+

 

In AMERICA!!!!!!!!!!!

the NZ in NZ_87_TURBO does actually stand for something!!!!!!!!!!!!!!!!!!!!!!!!!!!
its 1500 in NZ!!!

and come on mate, you obv read through the post, the fact that i already stated that i was in NZ illude you did it?

 

Well, that's a little smaller then I expected lol

I'd go with stock primary and 800secondary in that case.........was his 12A stock port? If so, the 800's should do you fuel needs fine......could probably even just run the 750's in the secondary position and have enough fuel.

But FWIW......a set of 550/560's should NOT get 300rwhp by my calculations. *Maybe* 300 at the flywheel, but thats it.

EDIT- added "not" to the last scentence lol

 

yea thats what i was thinking. I just wanted to know if i needed to go upto 1000's or not.

no its not a 12 stock port, mine isnt a stocker either. I dont actually know what it is which sucks. it was stated its a stage two, which is a NZ term and reflects what you guys would call a big street port or a extended port, BUT on visual inspection of the port runners i can only see porting work done on the secondays. so i actually dont know.
got 3mm seals also. never mind

 

You need to find out how much power to expect for that set-up. Then you can work out how much fuel you need. You can't really get that from just a boost figure.

The S-AFC definitely won't handle them. A 550/1680 combo at the lowest correction (-50%) would still be richer than stock, and you probably would've detonated from massively over-advanced ignition timing well before then anyway.

Most injectors in Japanese cars are from Denso (including the FC's), so yeah, they're okay,

Nope, that's for idle mixture only.

 

hey i'll be boostin' my BNR Stage II on my S5 this spring. think it will be quite the same amount of air with your hybrid turbo, so:
my setup (after weeks of research) will be two 800cc SARD primaries and two 800cc SARD secondaries. i'm going to correct them with my SAFC!
you can get the SARD injectors quite cheap from www.RHDJapan.com!

sorry to drag this back up from page 5, but i didnt come on over the weekend.

Jason, wont adjusting the idle mixture enrichen or lean out the idle? if so then thats what i said.

I was thinking that it would be about a BNR stage 2 also.

so 800's all round you rekon? i was taking to another guy running a similar set up with 720cc all round using an FCON and a GCC and he was getting up to 11.5 AFR's so maybe 800's will do the job nicely

 

Yeah, just ignore me...
